Part 31

Start the mission, turn left, and go to the Coat Depository to speak with the Receptionist. You will obtain the Real WWI Pistol during a cutscene (a non-interactive cinematic the game plays automatically).

Head to the Lobby Restroom southwest of the Receptionist. Find a Container and a Civilian.

Wait for the Civilian to leave, then position yourself in front of the toilet closest to the Container. Prepare your Sedative.

A Worker will enter the Restroom to use the toilet. When the door closes, Sedate the Worker, change into a Worker Disguise, and hide the body in the Container. Exit the Restroom.

Go north, climb the main stairs to the 2nd Floor, then head northwest to the spiral stairwell leading to the 3rd Floor.

On the 3rd Floor, head southwest towards the Guards Quarters. Wait for a Guard standing by the "Tosca" poster to leave.

Enter the Guards Quarters and pick up the MP5 and the SLP .40 Pistol (if you don't have one). Exit and use the spiral staircase to descend to the 1st Floor.

Turn right on the 1st Floor to find a Worker painting a door. Go through the nearby open door and descend to the Basement.

In the Basement, locate a large panel on the floor and pick up the Nailer (it will automatically be prepared).

Turn around and go back to the door you entered from, but take the short stairs to the left. Turn right at the next corner to find double doors.

Go through the double doors, then through a single door on the left that leads to the Stage area. Head up the stairs.

Go through the large dressing room and the double doors into the Backstage Hallway. Turn left and enter the next door, which leads to a small Restroom.

Wait by the single toilet. A Worker will enter from the Backstage working area. Use the Nailer on the Worker when they attempt to use the toilet. Leave the body as no one else enters this Restroom.

Exit the Restroom and head south down the Backstage Hallway. Stand by the third door on the right wall, marked with a silver star, but do not enter.

A Bodyguard is napping in a chair ahead. He will periodically go to the southern Restroom or, depending on your speed, to the Stage. Wait until he leaves the area.

Enter the Dressing Room, equip the Real WWI Pistol, and hide in the Closet.

When the Bodyguard leaves for the Stage, actors will take a break. The actor who performs the execution with a Prop WWI Pistol will enter this room.

After the actor rehearses and places the Prop WWI Pistol on a table, they will head to the Restroom.

Exit the Closet, wait for the door to close, and go to the table with the Prop WWI Pistol. Place the Real WWI Pistol on the right side of the table, pick up the Prop WWI Pistol, prepare your Sedative, and exit the room.
